Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of non-contact type steel strip plate profile instrument referring to FIG. 1-2, including fixed bracket I 1, fixed I 1 top of bracket are fixed
Laser emitter 2 is installed, the laser beam that laser emitter 2 emits is reflected on laser pickoff 4 by strip 3 to be measured, is swashed
The side of optical receiver 4 is fixedly connected with the side on fixed II 7 top of bracket, and the left and right sides of strip 3 to be measured is equipped with stone roller and pricks
Roller 5, the top of fixed bracket II 7 are fixedly installed with signal processor 6, and the inside of signal processor 6 and laser pickoff 4 it
Between be electrically connected.
Specific embodiment one:
The laser beam receiving area of one group of fixation is set in laser pickoff 4, when the flatness of strip 3 to be measured meets life
When producing the requirement used, the laser beam reflected from strip 3 to be measured will be irradiated in specific region, when strip to be measured
When flatness in 3 differs greatly, it will be changed according to the angle of the principle that light reflects, reflection, so as to cause anti-
The irradiation position for penetrating laser deviates specific region on laser pickoff 4, and then determines that the flatness of strip 3 to be measured is unsatisfactory for giving birth to
The requirement used is produced, sounds an alarm and records its timing node, and staff is reminded to make adjustment.
Wherein, according to the scanning range of the received reflection laser of laser pickoff 4, it is possible to determine that go out the song of strip 3 to be measured
Degree is stuck up, and strip to be measured 3, according to the roughness on its surface, can not only occur mirror-reflection, also can in reflection laser beam
Diffusing reflection occurs, thus according to the received laser intensity of laser pickoff 4, compared with the laser intensity of transmitting, so as to count
Loss amount of the laser in diffusing reflection is calculated, and then the surface roughness for determining strip 3 to be measured can be calculated.
In the technical program, the setting angle of laser emitter 2 and laser pickoff 4 with horizontal plane angle at 45 °, together
When laser pickoff 4 receiving area meet strip 3 to be measured laser when maximum warped is spent reflection scanning range.
Wherein, for the setting of laser emitter 2 and laser pickoff 4, it is ensured that the laser beam warp that laser emitter 2 emits
Any angle reflection for crossing strip 3 to be measured can be irradiated on laser pickoff 4, to be received by laser pickoff 4, be protected
Demonstrate,proved will not because the warped degree of strip 3 to be measured is excessive, and cause reflection after laser beam signal lose the case where.
Referring to Fig. 3, the bottom end of strip 3 to be measured can be set second group of laser emitter 2 and swash in the technical program
Optical receiver 4, and between two groups of laser emitters 2 with strip 3 to be measured for center line symmetry arrangement, and the laser pickoff of lower end
4 at being horizontally mounted.
Specific embodiment two:
Setting for upper and lower two groups of laser emitters 2 and laser pickoff 4 and its position, so that two groups of Laser emissions
The laser beam that device 2 emits can be radiated at the two sides up and down of 3 same position of strip to be measured, be reflected into two groups through strip 3 to be measured
In laser pickoff 4, to obtain two groups of different laser beam flying signals, then two groups of different laser scanning signals are defeated
It is sent in signal processor 6 by processing, so that it may the 3-D scanning image of strip 3 to be measured is obtained, it is further intuitive effective
The case where showing 3 flatness of strip to be measured.
In the technical program, the laser beam that the laser emitter 2 emits is strip structure, and the width of laser beam can be with
It is adjusted according to the width of strip 3 to be measured.
